Definitions

  • the invention concerns a mowing arrangement with a carrier that can be moved in the upward direction with at least one carrier part for the support of one or more mowing units.
  • Mowing arrangements in particular for grass, are provided with a mowing head whose inclination to the ground can be adjusted, in order to avoid the entry of stones or other foreign objects, in order to attain a particular height of the stubble and in order to create an equalization when the wheels of the carrier vehicle sink into the ground.
  • the adjustment of this so-called cutting angle is performed by a change in the length of the upper suspension arm in mowing arrangements that are connected to a front or rear three-point implement hitch.
  • a mowing head engages lower suspension arms so as to pivot vertically from a frame.
  • an upper suspension arm extends that can be varied in length in order to adjust the cutting angle of the mowing head relative to the ground.
  • An object of the invention is to provide a mower unit suspension that allows the cutting angle to be easily adjusted from an operator's platform, so that this is utilized optimally and the correct cutting angle is selected each time. For example, at the edge of a field a flat cutting angle of 0 degrees can be selected so that no stones or the like are picked up which could damage the mowing head or heads or contaminate the forage, while after the first pass of the mower the cutting angle is repositioned to approximately 4 to 6 degrees, so that the remaining stubble is not too high.
  • Such a repositioning arrangement that can be controlled remotely may be a mechanical linkage as well as a push-pull cable control, a hydraulic motor or an electric motor which, in particular, can be controlled electrically.
  • a more specific object of the invention is to provide a mower unit mounting including a first or base carrier part attached to the carrier vehicle so as to pivot vertically and so as to be loaded by a lifting arrangement, the lifting range being increased beyond the adjustment range of the cutting angle by a simple pivoting movement.
  • the bearings of, for example, a chopper drum attached to the carrier vehicle can be used simultaneously as bearings for the first carrier part.
  • Yet a more specific object is to provide a second carrier part pivotally mounted to the base carrier part for vertical pivoting movement about a horizontal transverse pivot bearing axis arranged above a remotely operable adjusting device such that a repositioning is also possible in cases in which the mowing arrangements, for example, with self-propelled mowing vehicles is modified, and is either not retained by an upper steering arm or no space is available above for an adjusting arrangement.
  • another object of the invention is to provide an adjusting arrangement for achieving a uniform repositioning of the cutting angle of several mowing units, this being possible if several mowing units are attached to the second carrier part, for example, two mowing units in a mirror-image arrangement.
  • This characteristic reduces the manufacturing cost and the operator effort.
  • the mirror-image arrangement and thereby the arrangement at an equal spacing from the carrier vehicle has the effect that a repositioning of the second carrier part leads to the same changes in the cutting angle.
  • a further object of the invention is to provide a mowing arrangement for high performance in a self-propelled configuration equipped with several mowing units that are arranged offset to each other in the direction of mowing, and including a cutting angle adjusting or positioning arrangement designed to avoid developing differing cutting angles due to lever arms of differing lengths by making provision for a further mowing unit attached, in particular by an arm so as to pivot vertically on the second carrier part or a fourth carrier part connected to it, and that a positioning arrangement is located between the first carrier part and the front-mounted mowing unit, so that a form of parallelogram linkage results which guarantees a parallel guidance and thereby to equal cutting angles on all mowing units.
  • the adjusting or positioning arrangement may be of invariable length, for example, a chain, a rope, a strut or the like.
  • the fourth carrier part that is connected with the second carrier part carrying the side mowing units, makes it possible to apply a standard mowing unit or a mowing unit as is otherwise applied in the mowing arrangement, and to attach it offset to the remaining mowing units.
  • the uniform movement relative to the ground is assured by the rigid connection with the second, movable carrier part.
  • Yet another specific object of the invention is to provide an adjusting or positioning arrangement as set forth in one or more of the previous objects and to further provide an arrangement of the transmission to the side of the adjusting or positioning arrangement which prevents it from touching or even damaging the third or the first carrier during a vertical movement of the fourth carrier part. Furthermore an unimpeded routing of drive shafts or the like is possible.
  • Still another object of the invention is to provide a mowing arrangement as defined in any of the previous objects wherein the use of a positioning arrangement between the second and the fourth carrier parts makes it possible to raise and remove the mowing unit attached to the fourth carrier part independent of one or more other mowing units and thereby to bring it into a non-operating position, or to overrun an obstacle without any other trouble.
  • Another object of the invention is to provide a mowing arrangement having, in addition to a cutting angle adjusting arrangement, as defined in one or more of the foregoing objects, a mowing unit mounted to a horizontally pivoted arm for making it possible, on the one hand, to increase the mowing width and, on the other hand, to reduce the width of the mowing arrangement for transport operation.
  • a connecting console that is, an adapter, a coupling or the like for the connection of the mowing unit with the particular arm, has the advantage that mowing units are easily dismounted and mounted and thereby can be replaced.
  • the connection in joints makes it possible that the mowing unit can conform to irregularities in the ground.
  • FIG. 1 is a plan view of a mowing arrangement mounted to a front end of a traction unit.
  • FIG. 2 is a perspective, left front view of a part of the framework for supporting the mowing units.
  • FIG. 3 a left side view of a part of the framework for supporting the mowing units.
  • FIG. 1 there is shown a mowing arrangement 10 constructed according to the invention and including a carrier vehicle or traction unit 12 having a main frame 76 to the front end of which several mowing units 14 are mounted through the agency of a common carrier frame 16 .
  • the mowing arrangement 10 is used for the mowing of grass or other crops and having a width of cut during operation of, for example, 9 meters, which lies considerably above the width allowed for the transport on public roads. For transport on public roads the mowing arrangement 10 is brought to a width of 3 meters maximum, as is described below.
  • the carrier vehicle 12 can be configured as an agricultural tractor with a front power lift or with a transmission and seat designed for reverse operating arrangement. But, the carrier vehicle 12 can also be a forage harvester, a combine or a self-propelled vehicle configured especially for mowing or others. In the embodiment illustrated, the carrier vehicle 12 is a self-propelled forage harvester with a front lifting arrangement 18 (FIGS. 2 and 3) and a configuration that is known from forage harvesters of the John Deere Company.
  • each mowing unit 14 is configured nearly identically and kept in the form of a known front mowing head.
  • each mowing unit is equipped with a mowing head that may be configured, for example, as a disk mowing head, drum mowing head or as a cutter bar. If desired, the mowing head can be followed downstream by a processing arrangement, for example, a stalk crimping or conditioning arrangement or the like.
  • each mowing unit 14 includes a housing 20 , a rear swath-forming arrangement 22 , a flange region 24 and a power-distributing transmission or gearbox 26 .
  • the housing 20 is generally configured in known manner and consists of a bolted or welded assembly of sheet metal plates and tubes, that is surrounded at its sides by plastic skirts and forms a rigid top cover.
  • the swath-forming arrangement 22 delivers the mowed and, if necessary, processed crop on the ground at the rear of the mowing unit 14 , and consists in the simplest case of converging swath boards oriented vertically.
  • a transport belt, a transport screw conveyor or the like is provided, that deposit the crop in a swath or windrow on the ground centrally or offset to the side of the mowing unit 14 .
  • the flange region 24 is located as close as possible to the center of gravity of the mowing unit 14 and can be provided with threaded bores, snap closures, hook closures or the like. In the embodiment shown the flange region 24 is formed by two equally large, transversely spaced, flange surfaces 25 . Each flange 25 has the same hole pattern of eight threaded holes.
  • the transmission 26 is located, in each case, on the left side of the mowing unit 14 as seen in the direction of operation, and is used to drive the mowing head and any processing arrangement that may be present.
  • the transmission 26 is provided with an input shaft 28 of a power transfer arrangement including pulleys or sprockets connected by tensioned flexible drive elements, not shown, for example, a belt or a chain.
  • a recess 30 is provided ahead of the input shaft 28 for an articulated shaft 32 , where the recess 30 need not be mandatory.
  • a further or power-receiving transmission 34 (side mowing units 14 ) or 34 ′ (central front mowing unit 14 ) that includes an output shaft 36 (side mowing units 14 ) or 36 ′ (central front mowing unit 14 ) and an input shaft 38 (side mowing units 14 ) or 38 ′ (central front mowing unit 14 ).
  • This further transmission 34 or 34 ′ is located off center with respect to the direction of operation of the mowing unit 14 and, in this embodiment, is also fastened, so as to be removable, to the right-hand flange 25 of flange region 24 , which, however, is not mandatory.
  • the further transmission 34 ′ that is mounted on the central front mowing unit 14 is configured as an angle drive transmission, and the further transmission 34 on the side or wing mowing units 14 is a spur gear drive or a belt drive transmission.
  • the input shaft 38 of the further transmission 34 extends through a transmission housing 40 and provides on both sides a stub shaft that engages an articulated shaft 32 .
  • the output shaft 36 is connected, although it may be disconnected, over the articulated shaft 32 with the input shaft 28 of the transmission 26 .
  • the output shaft 36 is located in the same plane on each mowing unit as the input shaft 28 of the transmission 26 , as seen transverse to the direction of mowing. Although their vertical alignment is desired, the present embodiment nevertheless provides a small vertical offset, where the inclination of the articulated shaft 28 is made possible since it enters the recess 30 . In the further transmission 34 ′ of the central or front mowing unit 14 , the input shaft 38 ′ extends perpendicular to the output shaft 36 ′.
  • a main drive transmission 42 which is arranged as an angle drive transmission in T-configuration.
  • the main drive transmission 42 is penetrated by a shaft 44 , that operates as an input as well as an output shaft.
  • a drive pulley 46 of a belt drive transmission 48 leading to a power source of the carrier vehicle 12 , is fixedly mounted on the shaft 44 for rotation with it.
  • a gear 52 configured as a bevel gear, is mounted, fixed against rotation, on the shaft 44 in a gearbox housing 50 , which meshes with a gear 54 also configured as a bevel gear arranged at a right angle to it.
  • the gear 54 is mounted on an output shaft 56 , which extends at right angles to the shaft 44 and to output shaft 36 ′ of the further transmission 34 ′ on the forward mowing unit 14 .
  • the two angle drive transmissions 34 ′ and 42 may be configured equally so that the input shaft 38 ′ of the transmission 34 ′ would become the input shaft and the output shaft 56 of the transmission 42 would become the input shaft if the transmissions 34 ′ and 42 were exchanged.
  • All input shafts 38 or 38 ′, output shafts 36 , 36 ′ or 56 , and shafts 44 are provided with a splined profile, that is not shown but is standard, on which a commercially available articulated shaft 32 can be mounted.
  • the shaft 44 that extends transverse to the direction of mowing and the input shafts 38 as well as the output shafts 36 and the input shafts 26 extend in one alignment.
  • the output shaft 56 of the main drive gearbox 42 is offset to the side of the input shaft 38 of the further gearbox 34 that is configured as an angle drive transmission.
  • an offset of the connecting points is possible within the limits existing for each of the articulated shafts 32 used. If necessary, wide angle joints or several articulated shafts can be used that extend at an angle to each other and that are arranged one behind the other, that are connected to each other, fixed against rotation, over a bearing, not shown, in the flange regions.
  • each of the mowing units 14 could also be performed over one or more hydraulic or electric motors whereby individual transmissions or all transmissions 26 , 34 , 34 ′, or 42 could be omitted.
  • the result is the following drive concept, where the assumption is that three mowing units 14 are used.
  • the drive is transmitted from the carrier vehicle 12 over the belt drive transmission 48 to the drive gear 46 , which brings the shaft 44 into rotation.
  • the shaft 44 is connected on both sides of the transmission housing 50 , fixed against rotation, over one articulated shaft 32 each with the input shaft 38 of the further transmission 34 , where, with the left mowing unit 14 , an exposed end section of the input shaft 38 projecting from the right side of the transmission housing 40 is connected to the associated shaft 32 , and, where, with the right mowing unit 14 , an exposed end section of the input shaft 38 projecting from the left side of the gearbox housing 40 is connected to the associated shaft 32 .
  • the drive is transmitted further to each of the output shafts 36 , if necessary with a step up or reduction in speed, which in turn is connected, fixed against rotation, over an associated articulated shaft 32 with the input shaft 28 of the transmission 26 .
  • the transmission 26 finally transmits the drive to the particular mowing head and, if available, processing arrangement. Accordingly, the drive of the mowing units 14 at the sides is performed, or its drive, in case only one mowing unit 14 at the side is used, without the main drive transmission 42 becoming loaded since the shaft 44 extends completely through the transmission housing 50 , which serves in the nature of a bearing support for the shaft 44 .
  • the drive of the central and the forward mowing unit 14 originates from the shaft 44 or the gear 52 fastened to it, which drives the output shaft 56 through the positive locking connection with the gear 54 .
  • the output shaft 56 is connected, fixed against rotation, over a further articulated shaft 32 with the input shaft 38 ′ of the further transmission 34 ′ on the forward mowing unit 14 .
  • a further articulated shaft 32 connects the output shaft 36 ′ of the further transmission 34 ′ with the input shaft 28 of the transmission 26 , so that thereby the drive of the mowing head and, if available, of the processing arrangement is guaranteed.
  • the layout of the gearbox 26 as a belt drive gearbox with belts permits, on the one hand, a guarantee of the drive train against overloads and, on the other hand, makes it possible to interrupt the drive of every mowing unit 14 independently of any other mowing unit 14 .
  • the arrangement and configuration of the further transmissions 34 makes it possible to replace a damaged mowing unit 14 by another, for example, of the existing combination.
  • An exchange of the mowing units 14 at the sides is possible without any change.
  • An exchange of the forward mowing unit 14 for one on the side is possible, provided the further transmission 34 ′ configured as an angle drive transmission is exchanged for a further gearbox 34 configured as a spur gear drive or belt drive gearbox or vise versa, which is possible without any problem due to the method of arrangement and fastening.
  • This ability to exchange without any problem makes it possible to react rapidly to any damage to a mowing unit 14 , so that a mowing unit 14 ready to be applied is always available, and is located ahead of the carrier vehicle 12 .
  • the separation of the mowing unit 14 from the carrier 16 is performed in the flange region 24 by means of bolts, screws, hooks or the like, not shown.
  • the carrier 16 is composed of several components, in particular, a first or base carrier part 58 , a second carrier part 60 , a third carrier part 62 and a fourth carrier part 64 , which are carried by the carrier vehicle 12 and can be repositioned in height relative to the ground by its lifting arrangement 18 .
  • the carrier 16 forms a unit with the mowing units 14 , that can be deposited on the ground or can be transported by the carrier vehicle 12 .
  • the first carrier part 58 contains two plates 66 that are spaced at a distance from each other that are connected to each other by a tube 68 so as to be connected rigidly.

  • the second carrier part 60 also includes two plates 80 that are transversely spaced from each other and joined together in their lower end regions by a tube 82 , of square or rectangular cross section, that projects beyond these to the side and is provided at its ends with a connection 84 .
  • the connection 84 is configured as a fork and includes a bore at its upper end for receiving a pin.
